Abstract
The invention relates to a ground glass flange filter, comprising a ground feed liquid flange (1) and a ground support flange (5), wherein the ground feed liquid flange (1) and the ground support flange (5) are in butt joint; an organic glass disk (4) with holes is arranged between the ground feed liquid flange (1) and the ground support flange (5); and a round filter paper sheet (2) is arranged between the ground feed liquid flange (1) and the organic glass disk (4) with the holes. By virtue of the ground glass flange filter, to-be-detected sediments can be directly filtered; sediment transferring and re-nesting are not required; and the ground glass flange filter is easy to operate and high in work efficiency.
Description
Technical field
The invention belongs to sediment filtration art, be specifically related to a kind of grournd glass Flange filter.
Background technology
In radiochemical analysis, usually need to measure the radioactivity in sediment.To sedimentary collection generally by the method for filtering, sedimentation and filtration filters with sand core funnel usually, or with common funnel pad Filter paper filtering.But the radioactivity in measurement sediment, needs sediment to be paved into the uniform regular shape of thickness (generally rounded).
After sand core funnel filters, need sediment to shift, then spread sample, pilot process sediment can not shift completely, needs to consider transfer yield.Common funnel pad Filter paper filtering, although arrived by sedimentation and filtration on filter paper, sedimentary out-of-shape can not directly have been measured, and same needs shifts and again spread sample.
Summary of the invention
For the defect existed in prior art, the invention provides a kind of grournd glass Flange filter, the sediment after filtration can directly be measured, without the need to transfer and paving sample; Simple to operate, operating efficiency is high.
For reaching above object, the technical solution used in the present invention is: provide a kind of grournd glass Flange filter, comprise ground feed liquid flange and ground pivot flange, described ground feed liquid flange and the docking of ground pivot flange, be provided with lucite disk with holes between described ground feed liquid flange and ground pivot flange, between described ground feed liquid flange and lucite disk with holes, be provided with circular filter paper sheet.
Further, described ground feed liquid flange and the dismountable connection of ground pivot flange.
Further, clip is adopted to connect between described ground feed liquid flange and ground pivot flange.
Further, the lower end of described ground pivot flange is provided with the bottle,suction for holding filtered fluid, and described bottle,suction is provided with rubber stopper, and the inside of ground pivot flange is inserted in the lower end of described ground pivot flange through rubber stopper.
Further, the joint of described ground feed liquid flange and ground pivot flange all adopts ground structure.
Further, the junction of described rubber stopper and bottle,suction all adopts ground structure.
Further, the top of described bottle,suction is connected with aspiration pump.
Advantageous Effects of the present invention is: filter of the present invention is compared with conventional filter, and the deposit sample thickness after filtration is even, can directly measure, and without the need to transfer and paving sample, improves operating efficiency; Ground feed liquid flange is connected with lucite disk with holes, seals tight, does not have side leakage; Ground feed liquid flange adopts clip to be connected with between ground pivot flange, for convenience detach; In addition, after filter replacement filter paper of the present invention, other deposit sample can be filtered, recycling, cost-saving.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, be grournd glass Flange filter of the present invention, this grournd glass Flange filter comprises ground feed liquid flange 1 and ground pivot flange 5, and ground feed liquid flange 1 and ground pivot flange 5 dock; Lucite disk 4 with holes is provided with between ground feed liquid flange 1 and ground pivot flange 5; Circular filter paper sheet 2 is provided with between ground feed liquid flange 1 and lucite disk 4 with holes.
Thus, the present invention, by adopting the grournd glass flange of docking, being provided with lucite disk with holes between two flanges, ensures that the deposit sample thickness after filtering is even, can directly measure the sediment on filter paper after filtration, without the need to shifting and again spreading sample, improve operating efficiency.
Ground feed liquid flange 1 and the dismountable connection of ground pivot flange 5, preferably adopt clip 3 to connect.Thus, adopt above-mentioned connected mode, namely ensure the air-tightness of whole filter, facilitate again the dismounting of whole filter, convenient operation personnel take out and change filter paper, simple to operate.
The lower end of ground pivot flange 5 is provided with bottle,suction 7, and bottle,suction 7 is provided with rubber stopper 6, and the inside of ground pivot flange 5 is inserted in the lower end of ground pivot flange 5 through rubber stopper 6.Thus, sediment will be filled on circular filter paper sheet, and filtrate flows in bottle,suction 7, avoids environmental pollution.
The top of bottle,suction 7 connects aspiration pump, when on-test, opens aspiration pump and is pumped into negative pressure state by bottle,suction 7, be convenient to filtering precipitate.
The joint of ground feed liquid flange 1 and ground pivot flange 5 all adopts ground structure, and rubber stopper 6 all adopts ground structure with the junction of bottle,suction 7, can ensure the air-tightness of filter process, prevent radioactive sample from spilling.
Bottle,suction 7, when filtering, is connected with vavuum pump, rubber stopper 6 is inserted bottle,suction 7 bottleneck by the present invention, and rubber stopper 6 is inserted in the lower end of ground pivot flange 5.Lucite disk 4 with holes is placed in the upper end of ground pivot flange 5, circular filter paper sheet 2 is placed in above lucite disk 4 with holes, the lower end of ground feed liquid flange 1 is placed on above circular filter paper sheet 2, is clipped together by the lower end clip 3 of the upper end of ground pivot flange 5, lucite disk 4 with holes, circular filter paper sheet 2, ground feed liquid flange 1.Open vavuum pump, inject the solution of band precipitation in ground feed liquid method 1, start suction filtration.After liquid is all through filter paper, close aspiration pump.Take off the circular filter paper sheet of band precipitation, be with the circular filter paper sheet of precipitation after simple process for analysis to measure.
In the analytical work of environmental water sample Strontium-90, caesium-137, obtain application, a large amount of environmental sample experiments proves, this filter is satisfactory for result to sedimentary collecting by filtration.
Grournd glass Flange filter of the present invention is not limited to above-mentioned detailed description of the invention, and those skilled in the art's technical scheme according to the present invention draws and other embodiment belongs to technological innovation scope of the present invention equally.
